This result supports the extractivists’ statement that they avoid establishing

crops or pastures in forests with BN trees or other valuable extractive resources. Second-cycle sites showed a higher average regeneration density, but it is usually after the third cultivation cycle that the BN tree density becomes substantial. The impressive BN regeneration density at some of the sites with long histories of agricultural use (we registered up to 104 trees ha−1) is perhaps better explained by a combination of factors. At the end of each SC cycle, the mature crop is an attractive source of Hydroxychloroquine food to the agoutis (Balée, 1994). This phase of the crop cycle coincides with site abandonment for forest succession. The dense and entangled colonizing vegetation shelters the natural disperser activity of the agoutis (Silvius

and Fragoso, 2003) and is also a favorable microhabitat for seed and seedling establishment (Peña-Claros, 2001 and Uhl, 1987). The BN seedling has a large nutrient reserve and may survive for several years under low-light conditions (Zuidema et al., 1999) but it depends on large forest gaps to thrive (Myers et al., 2000). This light-gap condition also occurs in fallows, as measured by Cotta et al. (2008). However, it is the learn more frequency of SC disturbances in addition to the species’ resprouting capability that ultimately results in the higher BN densities of fallows relative to BN densities in the nearby undisturbed forest. Past agricultural for use did not appear in the PCA because it was included as a grouping variable. However, this factor directly influenced the regeneration density observed (Fig. 2b). The higher light intensities offered by pastures may favor the growth of BN seedlings (Zuidema et al., 1999), but the frequency with which pastures are burned is incompatible with forest succession processes. Burning degrades the soil fertility and homogenizes the environment, eliminating seedling-establishment micro-sites and making seed dispersal from the surrounding forest improbable (Uhl, 1987 and Uhl et al., 1988). The frequency of burning cycles, the absence of

fallow intervals, and the presence of grazing animals tend to prevent vegetation regrowth. These properties of pastures probably discourage Dasyprocta dispersal activity because we rarely found gnawed-open fruits in the pastures, even though they were abundant in SC fallows and crops. This finding reinforces our assumption that the successful colonization of SC sites by BN trees depends as much on the disturbance events as on the consecutive fallow periods. The fact that pastures established in sites previously used for SC presented a regeneration density almost as high as those sites exclusively used for itinerant agriculture does not invalidate this conclusion. To show this argument correct, we must consider the characteristics of the regeneration that occurred in pastures established in areas previously used for plant crops.

In these videos you can see that the family in their home play space constitutes the bulk of the video image, and the remote therapist operating from the clinic can be seen in the lower right-hand corner of the screen. The mother in these videos is wearing a wireless Bluetooth earpiece receiver during the coaching so that she, but not her child, can hear the therapist’s live feedback. The viewer may notice that for this particular family, due to the home’s floor plan,

it was not an option to close a door at the entrance to the room. For this particular child there were no concerns about the child leaving the room—however, if there were such concerns we would have had the family move the couch Tanespimycin mw across this website the large open entryway in order to help the child remain in the room for the duration of the session. Video 5 illustrates an

I-PCIT therapist reviewing a family’s progress across treatment with a mother using a desktop sharing function. Whereas most of I-PCIT entails the use of both audio and video communication, using the desktop sharing function in videoconferencing software allows the parties to retain audio communication while temporarily suspending video communication so that both parties can jointly review a document that is open on one party’s screen. In this clip, the I-PCIT therapist is reviewing and explaining graphs that are open on his screen, and which the treated mother is able to simultaneously review. These graphs depict the treated mother’s increasing use across sessions of CDI “Do skills” (e.g., behavioral descriptions, labeled praises, reflections) and her decreasing use across sessions of CDI “Don’t behaviors” (e.g., questions, commands, and criticisms). Considerable gaps persist between supported treatments in experimental settings and services available in the community. Given

the enormous individual, familial, and societal costs associated with early disruptive behavior disorders, transformative efforts are needed to overcome traditional barriers to care and broaden the Glycogen branching enzyme availability of supported interventions. Across psychosocial treatments, behavioral parent training programs drawing on social learning theory have demonstrated the greatest support in treating early disruptive behavior problems (Comer et al., 2013). Among the supported treatments for early disruptive behavior problems, PCIT may be particularly amenable to a web format, given that by design the therapist conducts live observation and feedback from another room via a parent-worn bug-in-the-ear device. As such, live, Internet-based videoconferencing appears to be a particularly promising method for the delivery of PCIT to families underserved by evidence-based care. Herein, we have outlined the rationale and key considerations for the conduct of I-PCIT based on our extensive experience benchtesting and piloting these methods.

eluent for 20 fractions (PGB16+17-1–PGB16+17-20). PGB16+17-7 (370 mg, Ve/Vt = 0.18–0.20) was fractionated over the ODS column (φ 4 cm × 5 cm, MeOH–H2O = 3:1, 2 L) for 20 fractions (PGB16+17-7-1–PGB-16+17-7-20) including ginsenoside Rf [2, PGB16+17-7-16, 3.4 mg, Ve/Vt = 0.712–0.798, TLC Rf = 0.42 (RP-18 F254S, MeOH-H2O = 3:2), and Rf = 0.44 (Kieselgel 60 F254, CHCl3–MeOH–H2O = 65:35:10)]. Fraction PCI32765 PGB16+17-9 (1.7 g, Ve/Vt = 0.25–0.29) was separated over the ODS column (φ 4 × 6 cm, MeOH–H2O = 3:1, 7 L) into 36 fractions (PGB16+17-9-1–PGB16+17-9-36) including the 20-gluco-ginsenoside Rf [4, PGB16+17-9-12, 223 mg, Ve/Vt = 0.22–0.27, TLC Rf = 0.54 (RP-18 F254S, MeOH–H2O = 2:1), Rf = 0.31 phosphatase inhibitor library (Kieselgel 60 F254, CHCl3–MeOH–H2O = 65:35:10)] and the ginsenoside Re [1, PGB16+17-9-15. 68.3 mg, Ve/Vt = 0.38–0.40, TLC Rf = 0.50 (RP-18 F254S, MeOH–H2O = 2:1), and Rf = 0.36 (Kieselgel 60 F254, CHCl3–MeOH–H2O = 65:35:10)]. Physicochemical and spectroscopy data from each ginsenoside are in Table 1, Table 2 and Table 3. The purity

of the isolated compounds was over 99% as determined by HPLC and 1H-NMR. Most of the saponins were obtained as white powders, in agreement with most of the literature in which ginsenosides were obtained as white or colorless powders [7], [10], [15] and [19]. Preliminary experiments showed that more precise and accurate melting

points were obtained with the Stanford Research Systems melting point apparatus we used than with the Fisher-John instrument used previously. As a result, melting points determined in this study often differed significantly from values found in the literature. The melting points of ginsenoside Re (1) in the literature are from 168°C to 198°C [7] and [15], whereas the results of this study indicated a melting point of 186–187°C. The literature value for ginsenoside Rf (2) is 197–198°C [15], whereas this study found that it was 180–181°C. The reference-state [15] melting point of ginsenoside Rg2 (3) is 187–189°C in the literature, whereas it was found to be 191–192°C in this study. The reported melting point for 20-gluco-ginsenoside Rf (4) is 204°C [19], whereas this study found that it was 204–205°C. Significant differences from the values in the literature were also found for optical rotation. Ginsenoside Re (1) has an optical rotation of –1.0° according to previous studies [11], whereas it measured –1.80° in this study. Likewise, the optical rotation of ginsenoside Rf (2) is +6.99° in other studies [15], whereas a value of +13.80° was obtained here. The specific rotation of ginsenoside Rg2 (3) measured –3.84°, whereas the literature value is +6.0° [15]. For 20-gluco-ginsenoside Rf (4), the literature value is +21.0° [19], whereas the result obtained here was +64.00°.

Participants sat in a chair with a handle attached to the back to

Participants sat in a chair with a handle attached to the back to allow efficient movement between the frontal and abducted positions. The chair was attached to a rotating base on which plus and minus 40° and 20° were marked enabling the experimenter to accurately rotate the chair in either direction. Likewise, the chin rest could be rotated to ±40° and ±20°. The experiment was completed in a dark room. Participants used their dominant eye and their non-dominant eye was patched. Participants sat two meters away from the experimenter, extended their arms and brought their hands together in front of their eyes, leaving only a small gap through Venetoclax which they could see the experimenter’s nose. The eye that the

experimenter could see through this gap was recorded as the participant’s dominant eye. If the right eye was dominant, the left eye was patched and the participant was rotated to the left. Stimuli were presented on either side of a central fixation spot. In the case of the right eye being dominant, as shown in Fig. 1A, the temporal hemifield was the right side of the screen. There were six conditions: Frontal Temporal, Frontal Nasal, Abducted 20° Temporal, Abducted 20° Nasal, Abducted 40° Temporal, Abducted 40° Nasal. In the abducted conditions participants started each trial with their bodies and heads turned 20° or 40° to either the left or MLN8237 price right. After the presentation of

the stimuli they were rotated back to the front. This meant that participants encoded the stimuli in the abducted position but rehearsed it and recalled it in the frontal position. In the frontal condition participants faced forwards for the duration of the trial, thus the eye was in the center of its orbit throughout. In all conditions participants were required to fixate on a central spot (0.3° visual angle) for

the whole trial. Participants completed two tasks: the visual patterns task as a measure of visual memory; and the Corsi Blocks task as a measure of spatial memory. For each task, memory span was assessed four times in each condition across two testing sessions, with each session lasting approximately 1 h 45 min. In one session participants completed half the frontal spans (2 Frontal Temporal spans and 2 Frontal Nasal spans) and all the Abducted 40° spans (8 spans) per task, and in the other session they completed the remaining half of the Frontal spans and the Abducted 20° spans. The order of the two sessions was counterbalanced. Each session was divided into 4 blocks, two for each task, with each block containing 6 spans (two abducted nasal, two abducted temporal, one frontal nasal, and one frontal temporal per block). The order of tasks was counterbalanced across participants, as was the field of presentation (Temporal, Nasal) and Eye Position (Frontal, Abducted) within blocks. Participants completed three frontal and three abducted practice trials for each task. Nine boxes, arranged in a 3 × 3 grid, were presented (Fig. 2A).

g. Miller et al., 1999 and Taylor and Hudson-Edwards, 2008). Surface Enrichment Ratios >2 indicate surface soil contamination (cf. Taylor et al., 2010 and Mackay et al., 2013). Eighty percent of Cu floodplain SER values are >2, with a maximum of 8.8. Given that Cu was the

primary metal being extracted at LACM, these values demonstrate that the spill has had a marked impact on the floodplain surface relative to deeper sediment concentrations. Although the upper Saga and Inca catchment possess highly mineralised bedrock geology, the SER values signaling pathway coupled with a lack of sediment-metal variation at depths <2 cm confirms that the in situ geology is not a significant factor in explaining the surface enrichment of Cu. The Glencore Xstrata Mount Isa Mines Pty Ltd mining and smelting facility, one of the Australia's largest emitters of Cu to the atmosphere (∼46,000 kg in 2011–12; NPI, 2013), lies ∼140 km upwind of the study catchment. Parry (2000) demonstrated that, at distances greater than 50 km from the mining and smelting operations, surface soil metal concentrations returned to background levels. Therefore, it is unlikely that emissions from Mount Isa Mines have contributed significantly to the surface enrichment of Cu in the floodplain sediment. The effect of Cu contamination on floodplain sediment

quality is evident as far as ∼40 km downstream, but any residual effect has dissipated by ∼47 km downstream, where the Barkly Highway crosses the Saga-Inca catchment (Fig. 2 and Fig. 6). In contrast to Cu, the floodplain surface sediment concentrations of As, Cr and Pb are highly variable. Given that the majority of As, Cr and Pb concentrations Autophagy inhibitor mouse are below or near the mean background concentrations, Sclareol these are probably natural variations rather than the result of impacts arising from the mine spill. Although the vertical soil-metal profiles for Cr and Pb indicate a slight surface enrichment in 60% and 70% of pits, respectively, the SERs are <2, which could be attributable to natural variations in local sediment chemistry. In addition, As displayed no clear soil-metal profile patterns. Thus, considering variability in both lateral

floodplain sediment-metal and the absence of significant surface enrichment, it is evident that As, Cr and Pb cannot be used to delineate the effect of the mine spill. Furthermore, concentrations are below the threshold of concern with respect to Australian Sediment (ANZECC and ARMCANZ, 2000 – ISQG low and high) and Canadian Soil Guidelines (CCME, 2007). Soil-metal profiles for Ni and Al revealed inverse relationships to Cu, with an increase in concentration with depth. Given that Al is a structural element in clays, this increase with depth is probably due to in situ clay mineral variation (e.g. weathering) rather than anthropogenic influence (Siegel, 2002). The cause of the down profile increase in Ni concentration is less definitive.

Experimental and clinical studies increasingly show that alcohol-

Experimental and clinical studies increasingly show that alcohol-induced oxidative

stress is considered to be an early and indispensable step in the development of ALD [3]. Several pathways contribute to alcohol-induced oxidative stress. One of the central pathways is through the induction of cytochrome P450 2E1 (CYP2E1) by alcohol, leading to the induction of lipid peroxidation in hepatocytes [4]. Indeed, transgenic mice overexpressing CYP2E1 showed significantly increased liver damage following alcohol administration when compared with wild type mice [5]. By contrast, CYP2E1 knockout mice [6], and pharmacological inhibitors of CYP2E1 such as diallyl sulfide [7] and [8], phenethyl isothiocyanate [7] and [8], and chlormethiazole [9] decreased ethanol (EtOH)-induced lipid peroxidation and pathologic alterations. Chronic alcohol ingestion has been shown to increase levels of sterol regulatory element-binding protein-1 selleck (SREBP-1), a master transcription factor that regulates lipogenic enzyme expression, including fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC), and stearoyl-CoA

desaturase-1 [10] and [11]. Alcohol intake also lowered levels of peroxisome proliferator-activated receptor-α (PPARα), a key transcriptional regulator of lipolytic enzymes, such as carnitinepalmitoyl-transferase-1 and uncoupling proteins [12]. In addition to regulating transcription factors associated with fat metabolism, alcohol affects the activities of enzymes involved in energy metabolism, including Ibrutinib molecular weight adenosine monophosphate-activated protein kinase (AMPK) and sirtuin 1 (Sirt1). AMPK, a conserved cellular energy status sensor, is a serine–threonine kinase that can phosphorylate and subsequently

inactivate SREBP-1 in hepatocytes, thereby attenuating steatosis [13]. Expression of the Sirt1, nicotinamide adenine dinucleotide-dependent class III histone deacetylase, is decreased in mice fed with alcohol, resulting in increased levels of SREBP-1 acetylation [14]. In addition, hepatocyte-specific knockout of Sirt1 impaired PPARα signaling and β-oxidation, Ketotifen whereas overexpression of Sirt1 elevated the PPARα target gene expression [15]. Hence, the AMPK/Sirt1 signaling axis is a promising therapeutic target to attenuate lipogenesis and increase lipolysis in ALD. Korean ginseng (Panax ginseng Meyer) is one of the oldest and most commonly used botanicals in the history of traditional Oriental medicine. It has a variety of pharmacological activities, including anti-inflammatory, -tumor, and -aging [16]. The ginseng saponins, ginsenosides, play a key role in most physiological and pharmacological actions of ginseng [17]. Korean Red Ginseng (KRG) is heat- and steam-processed to enhance biological and pharmacological activities [18]. Red ginseng contains higher amounts of ginsenosides, and some ginsenosides are only found in red ginseng [19].

4). Due to its rarity, nonspecific Obeticholic Acid molecular weight symptoms and radiological findings, intracranial tuberculomas remain a clinical challenge. Misdiagnosis of tuberculomas as malignant diseases have been described in literature.4, 5, 7 and 8 Our patient was HIV negative, had a medical history

of malignancy and presented with multiple brain lesions so the first suspicion was also metastatic disease. Tuberculomas must however be always included in differential diagnosis of cerebral space occupying lesions. As the patient missed follow-up after his first TB infection this may be the case of a reactivation but reinfection is also a possibility and genotype was not performed. Regarding treatment, the Center for Disease Control and Prevention recommends 12 months of treatment for CNS TB when the MT strain is sensitive to all drugs.9 However numerous variables can affect the response of the disease Entinostat mw to therapy and it has been suggested that treatment duration

should be tailored to the radiological response.6 After 12 months of treatment more than two-thirds of the patients still have contrast enhancing lesions. Although it is not clear if this represents an active lesion or just inflammation, continuing treatment is probably prudent. Total resolution of the tuberculoma is observed when scans demonstrate no enhancing lesions or only an area of calcification.6 Systemic corticosteroids as adjuvant therapy are indicated when there is peri-lesional oedema or paradoxical progression during treatment. Surgical intervention may Sirolimus be necessary in situations with acute complications or when the diagnosis is not ensured.2, 3, 6 and 10 We would like to thank the careful editing of Flávio Monteiro, Papworth Hospital (Cambridge, England). “
“Hermansky–Pudlak syndrome (HPS) is a genetic multisystem disorder characterized by oculocutaneous

albinism, a bleeding tendency secondary to platelet dysfunction, and lysosomal ceroid accumulation.1 Ceroid, which accumulates sporadically and slowly in the lungs, is not crucial for a diagnosis of HPS, but primarily accounts for the significant associated morbidity. Pulmonary fibrosis, usually manifesting in the third and fourth decades of life, accounts for premature death in 50% of HPS patients, which generally occurs by the fifth decade.2 and 3 Nine different genes cause HPS in humans.4 and 5 Among them, the HPS-1 gene shows the highest frequency of mutation. HPS-1 mutation represents the classical disease, which manifests with all the typical complications of HPS. HPS-4 disease is considered to resemble HPS-1, but only a few case of HPS-4 have been reported.6, 7, 8 and 9 HPS-1 and HPS-4 individuals show the greatest degree of pulmonary involvement, with an estimated 80% of HPS-1 subtypes afflicted.6 and 10 Here, we report a case of HPS presenting with interstitial pneumonia and exhibiting a novel HPS-4 gene mutation.

Table 1, Table 2 and Table 3 show all studied variables and those that were selected for the multivariate logistic regression analysis with a p-value < 0.20. In Table 4, after adjusting for other socioeconomic variables, those that had a higher chance of neonatal

death were households with no children under 5 years of age and with fewer than four residents. The variables of Sections 2 and 3 that remained significant were mothers with a history of previous deaths of children in the first year of life and hospitalization during pregnancy, respectively. In Section DZNeP 4, the variables inadequate prenatal care, lack of echocardiography, newborn transferred to another health facility, and the longest time between hospitalization and childbirth were significant for the occurrence of death. In Section 5, NICU admission and low birth weight remained statistically associated with increased odds of neonatal death. There was a higher concentration of deaths during the first 6 days of life, with more than one-third of deaths on the first day of life. Neonatal deaths in the first 6 days are mainly caused by maternal factors and pregnancy and childbirth complications.6 Studies have confirmed the association

of these deaths with poor prenatal care and inadequate care to newborns in the Selleckchem ABT263 delivery rooms of hospitals.3, 16 and 17 Almost two thirds of the studied families had low income (less than two Brazilian minimum wages per month). The association of low individual socioeconomic status and risk of neonatal death has shown diverse results in analytical

studies in Brazilian cities.3, 18, 19, 20, 21, 22, 23 and 24 Family income, maternal education, and age were not Edoxaban shown to be risk factors for neonatal mortality in this study. Similar results were found in studies that used the same method,2 and 3 possibly because most of the mothers interviewed in this study were SUS users with homogenous household income and level of education between cases and controls. Mortality during the neonatal period is more influenced by the care given to the mother and child during pregnancy and childbirth, whereas mortality in the post-neonatal period is more related to socioeconomic status and, more specifically, to quality of life.10 Families with the lowest number of household members and absence of children under five years of age were associated with a higher chance of neonatal death, a result similar to that found in São Luís (MA), Northeastern Brazil, a city with a similar socioeconomic status to the city of Maceió.25 Mothers who lived with more household members to help with child care and mothers with more experience were the arguments used by the authors to explain this finding.

A 44 year-old male former heavy smoker was referred to our hospit

A 44 year-old male former heavy smoker was referred to our hospital for an abnormal chest radiograph and cough. He reported productive cough, fevers and night sweats for three weeks. On review of systems he had an unintentional weight loss of 40 lbs over the previous four months. He never had a tuberculin

skin test (TST) and denied tuberculosis contacts or wheezing. He was originally from Ecuador and had a history of right lower lobe pneumonia in the previous two years. A TST placed on admission was positive (20 mm). Decreased breath sounds on auscultation and dullness on percussion were appreciated at the right base. Blood tests revealed only mild leukocytosis (13,300 cells/uL) without bandemia. His basic GSI-IX molecular weight metabolic panel and liver function panel results were unremarkable. The patient’s posteroanterior and lateral chest radiographs are shown Protease Inhibitor Library clinical trial in Fig. 1A–B. Chest CT images (axial and coronal views) are shown in Fig. 2A–B. Pulmonary function tests were normal. Flexible bronchoscopy showed a smooth round white polypoid lesion with wide base at the distal end of bronchus intermedius almost

completely occluding the lumen (Fig. 3). White thick mucoid substance could be seen exuding from the right middle lobe bronchus. Our patient underwent bilobectomy and a biopsy of the polypoid lesion is shown in Fig. 4A–B. The diagnosis of an endobronchial leiomyoma causing complete obstruction of bronchus intermedius was made. Endobronchial leiomyomas are extremely rare benign tumors; Forkel reported the first case in 1909 [1]. They account for 33–45% of all pulmonary leiomyomas [2] and [3], U0126 solubility dmso and are usually found in young middle age patients (39.1 years in average) without sex predilection [2] and [4]. Clinical presentation depends on the location of the tumor, its size and changes in the lung distal to the lesion. Bronchial lesions produce symptoms due to partial or complete obstruction of the affected

bronchus, which may include wheezing, orthopnea, hemoptysis, recurrent pneumonia and subsequent bronchiectasis [5]. Kwon described cough, dyspnea and fever as major symptoms in pulmonary leiomyomas in the case series he reported [6]. Our patient had all of those symptoms. Endobronchial lesions comprise a heterogeneous group of pathologic entities (Table 1). Only 10% are benign tumors, papilloma being the most common form [7]. Our patient presented with recurrent pneumonia, significant weight loss and a positive TST, which lead to the presumptive diagnosis of active tuberculosis. However, sputum smear analysis was negative for acid-fast bacilli (AFB). Since endobronchial tuberculosis (EBTB) is sputum positive for AFB only in 16–53.3% [8], and out patient was originally from a high-endemic area, we decided to start empirical treatment for endobronchial tuberculosis.

The fluorescence index was calculated by subtracting the MCN of t

The fluorescence index was calculated by subtracting the MCN of the unstimulated cells from the MCN of the stimulated cells (PMA, zymosan and LPS). For data description, the mean and a 95% confidence limit were used. The Student’s t-test for paired samples and the Wilcoxon’s test were used for analysing the results within selleck chemicals llc each group, and the Mann–Whitney U test was used for comparing the results between the groups. Table 1 shows the details of the patients and control groups together with the PMs characteristics. 0.5–1.5 L of the ascitic fluid samples was used, which yielded an average total cell number of 2.24±0.87×104 cells/mL (Table 1). The fluid samples

from the control group were smaller, between 7 and 20 mL, and yielded a higher average cell number of 16.8±13.2×104 cells/mL (Table 1). The percentages of PMs in the cell mixtures were 85.2% and 91% (p>0.05) and the

percentages of viable cells were 92% and 94% (p=NS) for patients and controls, respectively. When the plates were examined using an inverted microscope following overnight incubation, we observed morphological changes that became more prominent in the plates to which GM-CSF had been added. The absorbance readings from internalised particles were expressed as percentages of arbitrary units (AU) (Section 4.4), and a standard mean value ±95% CL was obtained Ibrutinib concentration for each group. Fig. 1 shows the number of cases in which the absorbance readings fall within the corresponding absorbance range on the horizontal axis, where blue curve line represents patients’ PMs readings and green curve line represents control PMs’. The mean absorbance reading of the patient PMs (n=14) was significantly lower than that of the control PMs (n=12) (31.88±8.0% vs. 77.2±5.64%, p<0.01). The absorbance

in the patients’ PMs increased following particle second opsonisation (brown-red curve line, Fig. 1) (from 28.08±8.0% before to 41.24±13.35% after opsonisation, p<0.05), although the absorbance remained significantly lower than that for unopsonised control PMs (41.24% vs. 77.2%, p<0.05). Absorbance readings of supernatant fluid aspirated from the final plate washings, and representing non-internalised particles, were negligible (0.2–0.5%). A parallel qualitative observation was made when phagocytosis was assessed using direct microscopy examination and manually counting the ingested particles (data not shown). Pre-incubation of the patient PMs (n=10) with GM-CSF had insignificant impact on phagocytosis (30±9.4% before compared to 36±2.8.9% after, p=0.998). CD14 expression was significantly higher in the patient PMs than in the control PMs (180 vs. 118 MCN, p<0.05) ( Fig. 2). After IFN-γ treatment, the expression of CD14 was significantly downregulated in the two groups (from 180 to 80 MCN in the patient PMs (p<0.05), and from 118 to 20 MCN in the control PMs (p<0.05) ( Fig. 2).
